Does it work in Linux if you DON'T set $ENV{PATH} and
$ENV{ORACLE_HOME} inside your program? Are you sure they are
not set elsewhere in your environment?

Does it work in cygwin if you set them in a BEGIN { } block at
the top of the script. Quoting perlmod,

    A "BEGIN" subroutine is executed as soon as possible, that is, the
    moment it is completely defined, even before the rest of the containing
    file is parsed. ... Because a "BEGIN" block executes
    immediately, it can pull in definitions of subroutines and such from
    other files in time to be visible to the rest of the file. 

I thought the problem might be setting environmental variables in
perl perhaps only passes them to children of the process, but:

	greg AT 7106 ~
	$ perl -e '$ENV{hey}="what?"; print $ENV{hey}'
	what?
	greg AT 7106 ~
	$ 

shows this is not so.
